It appears that current logs in the FIDO server are mainly for debugging purpose, but they are logged in info level.
As a result, even if info level is configured in logback, they are always logged. When traffic rate is high, the server becomes busy for logging.
On the other hand, some logs passes parameters with manual string construction instead of {} placeholder, so the impact is even larger. (See https://www.slf4j.org/faq.html#logging_performance for details)
